Description

Technical Field

It has a high initial magnetic permeability and is generally used in the frequency range of 1 kHz to 10 MHz. It can be used to make inductors, transformers, filter cores, magnetic heads and antenna rods; it is usually called a ferrite core, and in actual use, the raw materials of the soft ferrite need to be ground using a ball mill.

[0003] According to the search, the patent number CN214974482U discloses a ball mill for the preparation of high magnetic permeability manganese-zinc ferrite, including a base provided with a first cylinder, a second drive, a second rotating shaft, and a second cylinder are provided on the base, a first through hole is opened on the second cylinder, a grinding protrusion is provided on the inner side of the second cylinder, a filter plate is provided on the outer side of the second cylinder, a third drive, a third rotating shaft, and a third cylinder are provided on the base, a second through hole is opened on the third cylinder, a grinding groove matching the grinding protrusion is provided on the outer surface of the third cylinder, a steel ball is provided in the third cylinder, a feed port is provided on the upper part of the third cylinder, and a discharge port is provided on the lower part of the first cylinder.
